ROLLER-CAGE Specication of Letters Patent.

Application led August 30, 1911. Serial No..646,816.

To all whom 'it may concern:

Be it known that I, GEORGE H. CARPENTER, residing at the city of Philadelphia,- in the county of Philadelphia and State of Pennsylvania, have invented aI .cert-ain new and useful Roller-Cage, o f which the following is a r specication.

The principal object of the present invention is to provide a roller cage capable of manufacture from a sheet of metal by stamping, pressin swagin' and like operations and which s all be lig t, strong, rigid, comparatively inexpensive and at the same time adapted to receive and retain the rollers and f present them properly for coperation with the various parts.V of a taper roller bearing.

The invention will be claimed at the end hereof but will be frst described in connection with the embodiment but not necessarily the only embodiment of it chosen for illustration in the accompanying drawings in which- Figure 1, is anelevational view looking at the smaller end of the cage and showing the rollers in application thereto. Fig. 2, is a sectional view of the same, and Fig. 3, is an elevational View looking at the larger end of the cage.

The cage consists of a sheet of metal of the form of a con-ic frustum having a series of axially disposed slots l. At the smaller end of the frustum there is a diametrically extending inward flange 2. This ilange2, is provided at its rim wlth projecting fingers. 3, capable of bein bent into substantial parallellsm with the eet, as shown in the drawings, after the rollers 4, have been inserted in place and capable of assuming enerally tion of the rollers. At the larger end of t-he conic frustum there is an inturned fold 5, provided at its rim with diametrically ranging .fingers 6, which are headed in the p sense that their side walls are somewhat concave as shown at 7, in Fig. 3@ From the foregoing description'it is evidentt-hat the cage can be made froma fiat ring or washerlike blank by stamping, swaging, pressing and like operations. The Walls of the slots l', and the side wallsof the fingers 3 and 6,

constitute r'oller pockets in which the rollers are retained in proper manner for coperating with the race-ways of the taper roller bearing and with flanges that may be formed thereon, that is to say, the conical surfaces of the rollers are exposed both inside and outside the cage and portions of the ends of the rollers are exposed at the ends of the cage.

What I claim as new and desire to secure by Letters Patent is: I

A roller cage consisting of a sheet of metal of the form 4of an vaxially slotted conic' frusturn having at one end a diametrically extending inward flange provided with projecting fingers capable of assuming substantial parallelism with the sheet and having at the other end an inturned fold provided with diametrically ran"ng headed lingers; and the walls of the s ots and the side walls of the fingers constituting roller pockets, sub-l stantially as described.

In testimony whereof I have hereunto signed my name in presence of two witnesses.
